HARRY VJ. MANNING, OF ?OBTLAND, OREGON.

OIL-BURNER.

Application filed. March 28, 1918.

To all whom it may concern:

" Be it known that I, HARRYVV. MAnNING, a citizen of the United States,and a resident of Portland, county of Multnomah, State of Oregon, haveinvented a certain new and useful Improvement in Oil-Burners, of whichthe following is a specification.

The object of my invention is to provide an oil burner of simple,durable and efiicient construction.

My invention particularly concerns the burner-head and in thisconnection has for its purpose to so construct the latter that it willdischarge a sheet of flame. This result I attain by providing the sidesof the burnerhead with circumferential slits instead of perforations;the latter construction having a tendency to become clogged, whichinterferes with the eiiiciency of the burner. Furthermore I make myourner-head of removable parts. My invention also has for its object theproviding of a burner Which shall comprise two or more burnerheads, someof which are provided with a, valve by which the flow of gas into suchhead can be cut out, when only a single burner-head is required to beused.

Another novel feature of my invention is to provide an air-inlet for themixing chamher of my burner and control such inlet by a valve Soarranged as not to be capable of closing the inlet entirely at any time,and hence admitting some air allthe time, thereby obtaining perfectcombustion.

Other features of my burner are hereinafter more fully described,reference being had to the accompanying drawings, in which:

Figure 1 is a front elevation of my burner;

Fig. 2 is a top view thereof;

Fig. 3 is a right-end elevation with re spect to Fig. i;

Fig. t is a longitudinal. vertical section, centrally taken, of that ofmy burner-heads which is provided with a valve for cutting the same outoi? service. also showing a portion of the gas mixing chamber;

ing the arrangement of the valve controlling the air inlet of saidchamber;

Fig. 9 is a cross-section on the line 9-3 of Fig. 2'

Fig. 10 is a sectional detail of the genera.- tor; and i Fig. 11 is across-section of the generator on the line 1l11 of Fig. 1.

My burner comprises a tubular body, a, provided with an ain-and-gasmixing chamber b, with which is connected the generator pipe 0,connected at (Z to the feed pipe of the source of supply of thehydro-carbon oil. The generator 0 is provided at its end 0' with aneedle orifice into the mixing chamher I). The mixing chamber 1) isprovided at the bottom with an air inlet c, which is controlled byavalve f, preferably or" the construction shown in Fig. 8; that is tosay, being so constructed that it cannot at any time entirely out ofithe admission of air through the inlet e, but to the contrary admittingsome air through the same at all times, for the purpose specified. Thevalve 7 is regulated by a rod 9. The mixing chamber b also has aremovable cover or top plate It, so as to facilitate the cleaningthereof.

The gas in the generator pipe 0 is vaporized by the gas'eznitted throughthe slits i of the plate The plate has channels is at its side, whichchannels are filled with asbestos to be saturated with alcohol whenfirst lighting the burner and heating up the generator 0. I The bod v a,is made with transverse battle partitions m. as shown in Fig. 42, and n,as shown in Fig. 9, so as to retard the flow of gas and cause theefficient serving of the nearer burner as well as the distant burner.The body, (1-,. is made with necks o, 0, constitutin passageways orconduits for the gas into the burnenheads go, 0. The construction of theburner heads is the same except that the dome of the hurner-head p ismade with a neck a, in which reciprocates the stem .9 of the valve .9.When the latter is arranged shown in Fig. 1-, the flow of gas into theburner-head p would he stopped, and hence this burner-head will be cutout of service. burner-head is to be thrown into service, the valve awould he lifted and so arranged that the transverse pin t of the stem isrests on the top of the neck an Each of the burner heads is made up ofthe following When. however. this details: The lower part a of theburnerhead is made with a peripheral flange on which to seat a ring 4).The ring has circumferential slits 'w, and back of these slits areintegral connecting bars 00. On the upper edge of the ring is seatedthev dome q. The slits w permit the flame to be emitted into acircumferential continuous sheet which produces much more effectiveresults than in the case where the sides of the burner-head merely haveperforations, and part of these perforations become'blocked and preventthe gases from being emitted through such perforations, and inconsequence breaking up the flame.

The body, a, has a removable elbow 1 to facilitate cleaning, the elbowbeing integral with the neck 7) ofthe mixing chamber and being connectedto the body, a, through the medium of companion flanges 2", boltedtogether.

3, 3 are the legs of the bin-nor.

The core of the generator pipe, 0, consists of a number of Wires rolledas in the case of picture wire, but each wire in itself being composedof a series of wires loosely interwoven, thus causing the roll of wiresto be porous and at the same time break up the What I claim is:

1. An oil burner of the type described, comprising a plurality ofburner-heads, a gas, chamber, gzs passage-ways connecting theburner-heads respectively with the gas chamber, the chamber beingprovided with a series of transverse battle partitions alternately atthe bottom and at the sides to thereby retard the fiow of gas andprovide a substantially equal feed for the nearer well as distantburner.

2. In an oil burner of the type described.

nastier? a burner head comprising a base-section provided with aperipheral flange, an intermediate section removably seated on saidflange and encompassing the base, the base section having a central gaspassage, a dome removnhly seated on the intermediate section, a valveremovablyseated on the outlet end of said gas passage and provided witha stem extending through. the cap and means for"'sl1p 0rting the valvein lift-ed position.

3. In an oil burner of the type described, a burner head comprising ahollow basescction, an intermediate section encompassing the base, theintermediate section being circumferentially slitted and having inwardlyloc 'ated narrow transverse webs con-- necting the parts separated bythe slitting, said webs adapted to space the intermediate section fromthe encompassed wall of the base section.

4. In an oil burner of the type described, a burner head comprising abase-section provided with a peripheral flange, an intermediate sectionremovably seated on said flange and encompassing the base, theintermediate section. being .circumferentially slitted and havinginwardly located narrow transverse Webs connecting the parts separatedby the slitting, said Webs adapted to space the intermediate sectionfrom the encompassed wall of the base section, the base section havingacentral gas passage, a dome re novably seated on the intermediatesection, a valve removably seated on theoutlet end of said gas passageand provided with a stem. extending through the dome, and means forsupporting the valve in lifted position.
